Tom Morello and his rap/rock supergroup Prophets of Rage had to move a planned prison concert outdoors on Wednesday (10Aug16) after they were banned from playing inside.
The politically-charged band, made up of members of Public Enemy, Cypress Hill, and Rage Against the MAChine, was booked to rock out for 800 inmates at a state prison in Norco, California in support of the Jail Guitar Doors charity, which provides musical instruments to convicts as a form of rehabilitation.
However, authorities blocked the gig, with officials at the California Department of Corrections ordering the shutdown "just before showtime", according to CBS Los Angeles.
Explaining the situation, Morello said, "We were denied at the last minute because apparently they got some calls from right-wing nuts in Sacramento who said they were going to foment rebellion. What we meant to do is come here to play a great show."
Instead, Prophets of Rage staged the show outside prison walls, and made sure to crank up the volume so the inmates could enjoy the music too.
The supergroup, which was formed in May (16), previously hit headlines last month (Jul16), when it performed a free protest gig at an anti-poverty rally in Cleveland, Ohio on the opening day of the city's Republican National Convention, during which controversial billionaire Donald Trump was officially declared the Republican Party's presidential nominee.
